摘要

Polydentate diazine Schiff base ligands derived from benzil dihydrazone (BDH) are excellent ligands in the design and synthesis of helical coordination complexes, due to the simplicity of their preparation, the coordination versatility of the -C=N-N=C- fragments and the ease of modification of their structural forms (Sreerama & Pal, 2005; Chowdhury et al. 2003; Bai et al., 2012; Patra & Goldberg, 2001). However, in contrast to the di-Schiff base compounds (the 1:2 condensate of BDH and an aldehyde), mono-Schiff base derivatives (the 1:1 condensate) from BDH have been much less investigated. Three examples of the latter have been reported by our group, i.e. benzil dihydrazone-N-mono(5-chloro-1-formyl-2-hydroxy-benzene) (BDHMHCF), benzil dihydrazone-N-mono(4-di-ethylamino-1-formyl-2-hydroxybenzene) (BDHMHDF) and benzil dihydrazone-N-mono(1-formyl-4-methoxybenzene) (BDHMMF) (Tan et al. 2015) (see Scheme 1).
